Efficient and safe drinking water in cities

A sustainable and liveable city requires safe, efficient and sufficient drinking water supply. While growing populations challenge the supply of sufficient clean drinking water for cities around the world, the Danish model for urban water supply may offer inspiration on how to supply high-quality water in a transparent and democratic manner.

Water is a scarce resource under increasing pressure. According to the UN, global water consumption will increase by 30 % by 2030 due to population growth and increased wealth. A safe, reliable, and efficient water supply is pivotal for flourishing communities, human health, ecological nature, development, and growth. 

Safe, efficient, and reliable water supply through proper water management 

Water consumption in Denmark comes entirely from clean, safe, and drinkable groundwater – even tap water is not chlorinated. Denmark’s water consumption has been reduced by almost 40 % since 1980 even though the GDP has grown by 75 % during the same period. Agriculture and industry account for nearly two-thirds of the total water consumption in Denmark. Significant reductions, especially in the processing industries, have reduced the sectors’ water footprint. 

Thanks to a highly efficient distribution system, bacteria, and other impurities are minimised and water loss in pipelines has been reduced to less than 8 % 

Energy-efficient water systems have reduced the energy needed for water treatment and distribution, contributing to lower carbon emissions. An increasing share of renewable energy sources in the Danish energy mix has contributed to lowering the carbon footprint of the Danish water sector further.

Partnerships for safe water supply 

Access to reliable and clean water supply is crucial for economic development and significantly enhances public health by reducing waterborne diseases and supporting hygiene practices. Danish authorities and private companies collaborate with partners around the world to support the development of a secure water supply in vulnerable communities. 

Equitable water distribution promotes social stability and prevents conflicts over resources. In agriculture, reliable water access increases productivity and food security. A good water supply improves the quality of life, making education more accessible and reducing time spent on water collection. It also helps protect the environment by minimizing pollution and conserving water resources.  

Moreover, resilient water supply systems are vital for adapting to climate change effects like droughts and floods, ensuring continuous access during extreme weather events. This commitment to water supply supports sustainable development goals related to clean water, sanitation, health, and sustainable communities, laying the foundation for a sustainable future.
